After avoiding sysadmin issues for four years, I upgraded from Kubuntu 18.04 to Kubuntu 22.04.  At first, a big disappointment as there was no jpilot in the repositories.  It doesn't help that I have a heavily customized version of Jpilot with vi-bindings that I need to build from scratch after applying a series of patches. However,  in the end it wasn't terrifically difficult and I thought I'd relay the steps. 1: Get build dependencies "apt-get build-dep jpilot" no longer works so I needed to get dependencies by hand. Despite being for version 20.04, the .deb packages for libpisock-dev, libpisock-9, libpysync1 available at https://www.jpilot.org/ubuntu-20.04/ all installed fine. The full list of dependencies at https://www.jpilot.org/requirements/ was used to install the remaining required packages ("apt-get install XXX"). 2: Get source code The source code is available at https://github.com/juddmon/jpilot. I happen to use Mercurial, rather than Git, but the version control tools can mostly interoperate these days.  No instructions given for how to clone a repository since that is specific to your VCS. Because I'm using some patches keyed to old versions of the code base I found it easiest to update to the tag "release-1.8.x". Next, I applied my series of custom patches with patch.  I found it useful to change the AC_INIT line in configure.in to bump the version number to my own custom 1.8.3 value. 3) Build code autogen.sh ./configure --OPTIONS make 4) Package code I found it easiest to modify jpilot.spec with a text editor to customize it for my machine. "sudo checkinstall --spec jpilot.spec make install" produces a .deb package ready for install. --Rik
